EFFECT OF SALINITY ON GROWTH OF POSTLARVAL PENAEID SHRIMP

Abstract

The effects of salinity upon growth of laboratory held postlarvae of white (Penaeus setiferus) and grooved shrimp (P. aztecus or P. duorarum) were studied. In 2 series of experiments at room temperature (24.5-26[degree]C), 100 postlarvae were held at each of five salinities, 2, 5, 10, 25 and 40%. Brine shrimp nauplii were the sole food source. Growth rate during the one-month period did not differ significantly among shrimp held at the various salinity levels. Survival was generally excellent at all salinity levels, including 40%. The results suggest that salinity per se does not limit the growth of postlarval shrimp at the temperature tested.[long dash]Z. P. Zein-Eldin.
